Mulegé

Once a mission settlement, this charming town of some 3,500 residents swells in winter, when Americans and Canadians fleeing the cold arrive in droves of motor homes. Amid an oasis of date palms on the banks of the Río Santa Rosalía, Mulegé looks and feels more tropical than other Baja Sur communities. Several narrow streets make up the business district, and dirt roads run from the highway to RV parks south of town.

Access to the rock paintings is good, though you must have a permit and be accompanied by a licensed guide. Tours typically involve a bumpy ride followed by an even bumpier climb on the backs of burros.
